Can you clarify the license of diff-lcs? #27

Hi,

I am a bit confused about the license since the LICENSE.rdoc states:

This software is available under three licenses:
the GNU GPL version 2 (or at your option, a later version),
the Perl Artistic license,
or the MIT license.

and lib/diff/lcs/ldiff.rb file states:

# This program is free software. It may be redistributed and/or modified under
# the terms of the GPL version 2 (or later), the Perl Artistic licence, or the
# Ruby licence.

Can you clarify what is right? Both?

Thank you.

The Ruby licence, as of 1.9, is essentially the disjunctive license of GNU GPL and MIT. The Licence document trumps regardless.

@halostatue I know, but now it suggests BSD as well, is that correct?

I'm not sure. I haven't followed Ruby’s licensing in a while. If I can ever get around to rewriting this with bits that I know 100% that I've written, I will be modifying it to be MIT only, as my preference.
